Dollar rises on expectations, but weak numbers may trigger QE3 move

* Dollar at 1-month low vs yen, near Friday's 6-week high vs euro

* USD up more than 4 pct vs EUR, rises 3.4 pct vs JPY, from recent lows

* Speech by key EU officials, including Weber may impact Monday trade

* Many US data due in week, analysts project better numbers

The US dollar strengthened across the board on Monday on expectations that better economic data this week will suggest that the health of economic recovery in the world's largest economy is satisfactory, but investors are also cautious that any negative surprise could trigger market worries about more bond buyback by the Fed, potentially sending the greenback to its recent lows versus major counterparts.

Value buying in major metals and oil futures seen on Monday also underscores the fact that bad news from the US could just increase the number of investors who will sell dollars for commodities. Despite sharp rises that lasted until first week of this month, most investors see strong fundamentals for many commodities.

Investors' view on commodities will also depend on fresh signals from the Euro zone and Chinese steps to curb inflation. But what would be more interesting is how that set of US data scheduled for the week to November 19 will turn around.

Many important EU officials, including Alex Weber of ECB are scheduled to speak on the first day of the Euro Finance Week held November 15-19 in Frankfurt, Germany.

Media reports interpreted comments by key Ireland officials on Sunday to suggest that the nation was not ruling out possibilities of a rescue package by the EMU, which helped the euro rise against most major currencies and prevent sharper losses versus the greenback.

Positive surprises on US economic data front could defer talks about a third round of quantitative easing (QE3) but otherwise, we will all likely see the dollar journey taking the southward route.

Consumer and producer price inflation, retail sales, housing starts - all for October, November industrial production and weekly data on employment environment are the key US data due. September wholesale sales and details of foreign investment in securities and October leading indicators will run the show from neighbor Canada, whose currency is also heavily vulnerable to the commodity prices.

Economists widely predict better numbers for most indicators.

The greenback pulled back from multi-month lows versus euro, pound and the Canadian dollar and was strong across the board in the week to November 12.

By about 0920 GMT on Monday, the US dollar strengthened to 1.3641 against the euro, from 1.3691 at close on Friday and stronger by 4.7 percent from a 9-month low of 1.4280 it hit on November 4. At its day's peak, the greenback was just 48 pips away from a 6-week high of 1.3572 reached Friday.
